绘制庞加莱截面图 在相空间中适当（要有利于观察系统的运动特征和变化，如截面不能与轨线相切，更不能包含轨线）选取一截面，在此截面上某一对共轭变量如x1和x.1取固定值，称此截面为Poincare截面，相空间的连续轨迹与Poincare截面的交点成为截点。(Poincare mapping sections in the phase space properly (should be beneficial to observe the system and changes in movement characteristics, such as the cross-section can not be tangent trajectory, but also can not contain rail line) to select a cross-section, in this section for a total of conjugate variables, such as x1 and X.1 take a fixed value, call this cross-section for the Poincare section, the phase space of the continuous trajectory of the point of intersection with the Poincare cross-section to become cut-off point.)

这是一份高阶统计量的资料，有相关的程序，目前高阶统计量是研究的热门话题，对于地震子波的高精度提取有重要意义。(This is a higher-order statistics of the data full of relevant procedures,and at present higher-order statistics is a hot topic which is very important and significant for high-precision seismic wavelet extraction.)

计算信号的Kolmogorov熵,计算信号的Kolmogorov熵,计算信号的Kolmogorov熵,计算信号的Kolmogorov熵(computing Kolmogorov entropy of signal)

（1）通过Simulink创建仿真模型；（2）配置相关RTW（Real-Time Workshop）参数；（3）通过RTW（Real-Time Workshop）自动生成C代码文件，并理解主要文件、接口函数和变量的意义；（4）在Visual C++中将生成的C代码作适当修改，编译运行并分析结果。((1) created by Simulink simulation model (2) configuration related to RTW (Real-Time Workshop) parameters (3) RTW (Real-Time Workshop) automatically generate C code files, and understand the main document, interface functions and variables significance (4) Visual C++ generated C code will be modified as appropriate, compile, run and analyze the results.)
